Hi All I thought I would join and share with you some 3D printing / models myself and a friend of mine have been trying to perfect for nearly a year now, and finally now are getting somewhere with them. The coaches are the Chesham set, I know there are at least one kit of them from London Road Models which are an etched brass kit, but are the wrong type I am looking for. As I model the Bluebell, as it is today, those of you who know the set, have been restored to as they were originally built (supposedly). plus also having 4 coaches in the set made it difficult even with London Road models who make the 3 coach set. With the 150th anniversary of the London Underground Metropolitan line I decided to start work on 3D printing a set of coaches which will be available individually, and in parts as I am aware it costs a fair bit, so to make it flexible I made all the part separately. After several failed attempts I joined up with a fellow 3D modeller/printer who was doing London Underground rolling stock and joined forces to actually get these finished... and so far I have had some good results. So far I have 2 coaches one already printed which is the All 3rd, and currently in test print Brake 3rd. The Composite coaches are currently in the design stages.
Every step is a step in to the unknown, not knowing the material and how best to treat it, having several spare pieces enabled me to work out the best way of preparing the surface.
Hopefully when Radley Models finishes their server swap then I get some transfers to finish the first one.

Correct as preserved, not originally built... although I keep being told as built, which is as you state is wrong, as it would have 5 compartments, up until they were rebuilt with luggage capacity which got rid of the once compartment down to 4.
A tad more progress, The coach chassis has now almost been finished, few small handles and things to add, and buffers left to paint, but generally it's not far off now. I received some Metropolitan Railway transfers from Radley Models a few days ago, and proceeded doing some proper modelling, as the first part was more a trip in to the unknown. Glazing and seats will be added next, trying some new methods on that to, also need to add plasticard for the floor of the coach. Due to the density of the material, it may not need additional weight adding but will see when it ventures to the test track in a few days.
Hi Rich No has nothing to do with the Model World program, I am aware of it though have seen it on Youtube a couple of times, but layout was built recently early 2000's has been in a couple of magazines, one later this year, a couple of mag's are watching progress on the coaches as they were interested in doing a feature on the layout and the coaches.. depends when I finish them mind you.
I have had a recent delivery of the next coach, Brake 3rd. I still need to complete checks, and assess it for print checks for any faults or errors with the print, these will be checked with Shapeways and any adjustments recorded, I am already very pleased with the new strengthened bogies.
Not said much for nearly a month a bit of an update. All 4 carriage bodies have been made in CAD, so over the next month or 2, I will have all 4 complete hoping there are no problems to compared to the number I have had with this Brake 3rd. The Brake 3rd has been re-printed now twice, second in print at the moment, mainly down to it's orientation and position in the printer which I hope has now been resolved. Mean while on the all 3rd, It is nearly complete apart from its vac pipes ect.... Comet jumper cables have been fitted to the ends, and a few touch ups and changes to the paint and it's pretty much there... I plan to change the bogies for the redesigned stronger type, as it's still on its original which were pretty weak.
Gosh, these are lovely, well done. Just thinking, I model in N Gauge, and am wondering how difficult it would be to "adjust" these and print in 2mm scale instead of 4mm. Not that I have any of the skills needed to do it, mind.
One has now become 2, I received the last print of the Brake 3rd which has now been finished and test run with the other, they both had 3 hours non stop running with no problems so I call that a pass.... and a step closer to making them available. I also half finished another 3D print project, my GN Saloon... which is slowly getting towards being complete.
In the final part of this project now, the first of the 2 composites have been completed, making the set 3 coaches. A start on the second Composite has now started and will be complete in a few days time.
I have just started finishing off the final composite coach in this set, which has been a bit of a struggle in recent weeks due to the failure rate from Shapeways.... Because of this I chose a different route on this last coach which was due to be finished at the end of June.. now in July I went with a local 3D print company called Graphite Additive Manufacturing, a company that does more checks on a print than you can think about.. which I like! This last coach has been printed by SLA printer, so a laser curing resin to create the model. I picked up the final print on Wednesday, and the quality was quite amazing, despite missing some smaller bits which was due to them being under the minimal print margins, the model was a lot smoother, the material is called ABS-Like.. although looking at other companies I Materialise does some thing similar called Prime Grey. It maybe double the cost but if your looking for a decent finish on a model then you have to be prepared to pay for it. SLS Nylon - £23 SLA ABS-Like - £49 Anyway I hope to finish this model by the 19th July hopefully in time for High Wycombe club open day. Here's some following images of the new print,
So after a year and a half, finally all of the 3D printed coaches are complete, apart from adding a few people which can be done later on. The 3D printed Metropolitan Set have taken a year and a half to complete.... hopefully will run for the first time as a full set this weekend, at the Wycombe Model club's open day... Also the GN saloon is now complete and running reliably.
This will most likely be the last year for the layout, which will be stripped and rebuilt to a better standard, and hopefully bigger
